### Constructing a Dependent / Independent Curve

If you select inappropriate feature types, PC-DMIS displays "Cannot construct [feature]. Combination of input features not accepted." on the status bar.

To construct a curve:

1. Access the Construct Curve dialog box (Insert | Feature | Constructed | Curve).

2. Input the desired set.

3. Set the value in the Thinning Tolerance box.

4. Edit the control points if necessary.

5. Click the Create button.

All constructed curves start out as DEPENDENT curves and must be created from a single input, a set. The set can be one of three types:

- A measured set

- A constructed set

- A scan containing a single row of points. (See "Constructing a Set of Features".)

The input set must contain at least four features or points (in the case of a scan).

The resulting curve depends on the order that the features are added to the set (first to last).

You can also construct a curve by simply selecting multiple features from the feature list box rather than selecting a constructed set from the list. In this case, the command's INPUT_TYPE field will be empty when viewing the command in the Edit window.

The following paragraphs describe the options for constructing a curve.
